💡 What is a pillow block bearing used for in industrial conveyor and shaft applications?
A pillow block bearing supports rotating shafts and keeps alignment while protecting a sealed ball bearing insert from contaminants. It makes shaft mounting and maintenance quick and handy for shop and plant use. Here’s why they’re used and where they help most: - Provide radial shaft support and secure mounting for conveyor, fan, and gearbox shafts using a sealed ball bearing in a cast iron housing - Allow on-shaft locking (set-screw style) and easy relubrication via a 1/8-27 NPT grease fitting for longer life - Fit common linear slide unit and industrial drive setups where a wide inner ring and heavy duty housing are needed
